Access SQ is an economical, reliable low-backlash planetary gearbox.

The planet carrier is a cage, which provides stiffness and acceleration capacity. It is monobloc with the output shaft.

High radial loads can be accepted thanks to the 2 radial ball bearings supporting the shaft.

The planetary ring is monobloc (belongs to the housing), to reinforce stiffness.

This construction improves acceleration capacity and acceptance of torque variations.

We recommend this line for applications using application factor Ka<1.45 (refer to the information section for more details about application factors).

 

 

 

 

 

In 2 stage configurations (ratios 12 to 100), the input stage is cantilevered (does not use a cage), in order to lower the intertia, the weight and the length of the gearbox. The output stage always includes a cage, in order to provide stiffness and longer life in heavy-duty conditions.

 

The motor shaft connection is a balanced coupling, so the efforts on your motor bearings are minimal.

 

Installation is fast and easy thanks to a 1-screw lock to your motor shaft.

 

The gearbox will be delivered with the adapting flange corresponding to your motor.

Note : all torque ratings fluctuate with the radial and axial loads that are applied on the shaft. Consult us to know the torque applicable in your application. Click here for more information.

1. Calculation based on the ISO 6336-2 standard (life = 20,000 h, speed = nominal speed, internal temp = 60°C , Application Factor = 1,25).
2. Calculation based on the ISO 6336-2 standard (life = 2,000 h, speed = nominal speed, internal temp = 60°C , Safety Factor = 1,4). This rating will not provide a 2,000 hours life if used at max speed. Contact us to get an estimation of the product lifetime in your application. Using a torque higher than the rated torque may affect the gearbox precision.
3. 1000 occurrences maximum. 
4. Speed at which the nominal torque is applicable 20,000 hours.
5. Peak speed only. 
6. Applied at the middle of the output shaft at 100 rpm.
7. Measured at full load and at 25°C
8. Lifetime at nominal torque and speed. Consult us to obtain a free estimation of lifetime in your working conditions
9. Room temperature. Refer to temperature factors in dedicated section.
10. At nominal speed, measured at 1m.
